^Yes we are severely restricted on the wings. However, we must have at least 2 systems of play that needs to be drilled in well enough to be used tactically against big teams. SPAL is a good opportunity to try to get the 4-man defense right. Using the flanks won't work - I agree. It should be more a 4-3-1-2 with Hakan in the hole, or a 4-3-2-1 with Hakan and Suso supporting the striker.

But Montella could easily choose to go 4-3-3 with Borini and Suso on the flanks again and try to get that right - if he feels the Lazio performance was due to other reasons and not tactical.

Basically, I won't be surprised if this match is used to get the alternative tactic to 3-5-2 right.
